Anyone come across or tried using the TIS 999 speeditest. CEF have them on sale in their shops. It claims to save up to 20mins on testing each ring main. All the tests are carried out from one point of connection, either the board or a socket. However, my concern is how can you say you've adequately tested out all the tests on a ring main from one point?

Anything that gets between the test meter and the circuit being tested is almost certainly going to introduce additional resistance and problems associated with poor connections etc.

It may look fine on paper and work in theory but in practice it is probably not a good idea..... unless the "electrician" doesn't know how to operate the meter and place the leads to conduct the tests correctly.

That's my point entirely, I don't think it is a good idea as it reduces testing a ring to one point only, which some I dare say think is adequate, whereas your still going to need to test R1R2 and R1Rn at each point to ascertain whether there are interconnections and spurs etc.

I believe metrel make a meter which does the same thing but automatically within the meter. If speed of taking readings is what your after, maybe it's got a place, but personally I find it quick, easy and thorough to test my ring and cpc continuity at a socket outlet, then figure eight link using the sockets terminals and manually check readings at all the outlets on the circuit.

I guess if you have guys on site doing instalation and testing, then it could be usefull as qs to quickly check the numbers aren't made up.
